CAR-REPLACER.

SPECIFICATION forming part of Letters Patent No. 257,827, dated May 9, 1882.

I Application filed March 23, 1882. (No model.)

.T 0 all whom it may concern:

Be it known that I, JOHN E. Nonwoon, a citizen of the United States, and resident of Sykesville, in the county of Carroll and State of Maryland, have invented a new and valuable Improvement in Oar-Replacers and I do hereby declare that the following is a full,

clear, and exact description of the construction and operation of thesame,.reference being had to the annexed drawings, making a part of-this specification, and to the letters and figures of reference marked thereon.

' a bottom view of the same.

Figure 1 of the drawings is a representation of a railroad, showing my improvement attached. Fig. 2 is a cross-sectional view of the same. Fig. 3 is a side view of the replacer. Fig. 4 is a similar view, and Fig. 5 is Fig. 6 is a sectional detail view.

This invention has relation to devices for replacing derailed cars on the track; and it consists inthe construction and novel arrangement of the centrally and obliquely ridged plates, slanting laterally toward the rail-edge and inclined toward each end longitudinally, the latter inclination and the lateral slant easily merging into eachother, the center post or support under the ridge, its holding I point or spike, and the longitudinal rabbet or groove under the rail-edgeof the plate, all as hereinafter set forth. I These plates are usually employed in pairs-one on the outside of one rail and the other on the inside of the opposite rail. The general formation of the two plates is similar; but they differ in regard to special features, as will be hereinafter explained.

In the accompanying drawings, the letter A designates the outside replacer-plate, and B the inside plate. Each plate is formed with a central oblique rise or, ridge, 0, which slants downward toward the rail edge d. From the ridge 0 the face of the plate inclid'es toward each end, as indicated at e, the back edge, g, of the plate being always higher than the front edge d, which is adjusted to the rail. Under the central ridge, G, is formed a pillar or support, H, which is designed to rest on the tie, and is provided with a spur or spike, k, to engage the-tie andhold the plate in position. Spurs or spikes may also be provided under the plate, near each end; or, notches may be formed in the ends of the plate, to engage spikes which may be driven into the ties. The rail-edge d of each plate is grooved orrabbetedlongitudinallyunderneath,

"as shown at m, to afi'ord a raised edge bearing or extension to fit over the flange of the rail, covering the heads of the rail-spikes. Each way from the center post under the ridge the plate is made comparatively thin, so that it can be easily transported, the wing portions being designed to be as light as possible consistent with the necessary strength. The rail edge of the outside plate is centrally higher 5 than the inside plate, and just back of said edge a valley or groove, o, is formed to receive and guide the flange of the wheel, which, as the car moves forward, rolls in thegroove upward toward the ridge, which, although its '70 lateral slope is steep, is obtusely rounded from end to end. Therefore, althouglrthe weight of the car is on the flange of the wheel bearing in the groove '1) of the plate until the flange is raised to the level of the top of the rail, the bearing is then transferred to the tread ofthe wheel and the rounded inclined slope of the plate to lift the flange over the rail to the inside thereof.- The inside plate, B, is usually made wider than the outside plate. The slope of this plate is not rounded longitudinallyover the ridge, as in the outside plate, but runs up rather sharply and quickly, forming a more de fined ridge, as shown in the drawings. While the outside piece will sustain the weight in .85 replacing a car near its rail-edge, the inside plate will be engaged further from its rail-edge, and therefore should be made comparatively thicker in the wing portions. In forming the outside plate the under groove at the edge 0 next the rail does not extend entirely to the end of the plate, because the plate is notched at each end to fit the flangeclosely, and atthe same time to provide a bevel surface as near as possible to the flange of the rail for the re- 5 ception of the flange of the wheel.

Having described thisinvention,whatIclaim, and desire to secure by Letters Patent, is-

1. The car-replacer consisting of a plate centrally and obliquely ridged, at 0, and inclined ICO tral obliqueridge, (J, rounded from end to end toward each end, as at 0, the center post or supback of said edge, and the. center support, H, 10 port, H, its-holding point or spike k, and the substantially as'specified. A rabbet 0r groove m under the projectingedge d, In testimony that I claim the above I have substantially as specified. hereunto subscribed my name in the presence 2. The outside replacer-plate having the cenof two witnesses.
